Sensor Data Pro vs Battery Coach

Sensor Data Pro helps you capture high-quality sensor recordings from your iPhone or iPad for testing, field work, and analysis. Use it to record motion, location, microphone level, barometer, and magnetometer data in one session. Add event markers as you record, review sensor charts by type, inspect per-axis values, and export complete session files for downstream analysis. Built for reliable long sessions: - Live preview before recording - Configurable sensor selection and sample rate - Background-aware recording behavior with explicit gap annotations when iOS limits sensors - Session analytics dashboards with min/mean/max and timeline context - CSV and JSON export from persisted recordings Your recordings stay on-device by default.

Battery Coach helps you build charging habits that protect your battery's long-term health — right on your iPhone. • Set a charge target (default 80%) and get a gentle alert when you reach it • A low-battery nudge when you're under 20% and Low Power Mode isn't on • A heads-up when your phone is overheating during charging • A home screen widget showing your battery level and time-to-target at a glance • A Live Activity that follows your charge on the Lock Screen and Dynamic Island • A weekly report with simple, rule-based coaching based on your actual charging history Your battery and charging data stay on your device — there's no account and no server. Battery Coach shows a small banner ad, served through Google AdMob, to keep the app free; see our privacy policy for details on how that works and how to manage your ad choices.
